Stars' Valentine's Day Horror Stories!

Read on for Hayden Panettiere, Lauren Conrad and the other stars' Valentine's Day horror stories.

Hayden Panettiere"I went through a bad breakup and spent the day at a restaurant called Birds, where they had an anti-Valentine's Day party. You can hang up notes like I HATE HIM or HE WAS MEAN TO MY DOG and make a voodoo doll out of your ex and poke it."

Jessica Biel"In fourth grade, I made the big huge card for a boy. I found it in the trash later in the day. It's cool. It's fine. I feel like I am better for it…not that I'm still thinking about it or anything."

Khloe Kardashian"My worst Valentine's Day ever was, I think I was like 17, or 18, like the love of my life, like my boyfriend who I was obsessed with in love, my first love, left me on Valentine's Day and moved back home. He just left -- like never said anything. Who leaves on Valentine's Day when you have a girlfriend that you're supposedly in love with? I get it. it was young love, but it really, really sucked, and I think it ruined every Valentine's Day from here on out."

Tate Donovan"I spent a ridiculous amount of money on a pair of Tiffany diamond stud earrings for a girlfriend -- it wasn't Jen Aniston! I gave them to her at dinner, and she burst into tears and said, 'You don't know me! I never wear studs, only drop earrings.' I was just, like, I can't win."

Lauren Conrad"In high school, I remember me and my friend were dating best friends and we went to a restaurant and we decorated the table and had presents waiting and had them meet us there on Valentine's Day and my date showed up drunk! I was really bummed. I put hours of work into it and he showed up drunk."
